Recipe Preparation

Crispy Onions

Whisk buttermilk and mayonnaise in a medium bowl; season with salt and pepper. Add onions and toss to coat; let sit 15 minutes.

Meanwhile, fit a large saucepan with thermometer; pour in oil to measure 2". Heat over medium-high heat until thermometer registers 375°.

Whisk flour and chili powder in a shallow dish; season with salt and pepper. Working in batches, remove onion from buttermilk, letting excess drip back into bowl, toss in seasoned flour, and fry, turning occasionally, until golden brown and crisp, about 4 minutes. Transfer to a wire rack set inside a rimmed baking sheet; season with salt.
